Definitions

  • This invention relates to slide fasteners, and more particularly to a slide fastener with a pair of stringers which are normally separated completely from each other by pulling a slider down along rows of interlocking fastener elements to a separable bottom end fitting on the stringers but which, in an emergency, can be readily separated from the top ends thereof without moving the slider to the bottom end fitting and hence without manipulating the latter.
  • the emergency opening fastener of this character finds typical application on sleeping bags or tents.
  • the present invention is directed to a slide fastener of the type comprising a pair of separable stringer tapes having opposed longitudinal edges beaded to carry rows of interlocking fastener elements which are progressively engaged and disengaged by a slider slidable therealong, and a slider escape mechanism including an extra length of fastener elements formed on the beaded edge of one of the stringer tapes as an upward extension of the regular row of fastener elements carried thereby, so that the slider can be guided onto the extra fastener elements in an emergency.
  • a reinforcing sheet of thermoplastic material or the like is substantially integrally attached to the other of the stringer tapes so as to cover its upper end portion in opposed relationship to the extra length of fastener elements on the said one stringer tape. At least the bead is removed from the upper end portion of the said other stringer tape, either before or after attachment of the reinforcing sheet, so that the slider when guided onto the extra length of fastener elements in an emergency, will readily release the upper end portion of the other stringer tape to permit the fastener stringers to be manually spread apart from their top ends.
  • the upper end portion of the stringer tape according to the invention is easy to prepare because it can be formed merely by means for attaching the reinforcing sheet thereto and means for cutting off at least the bead therefrom.
  • FIG. 1 is a fragmentary front view of an emergency opening slide fastener incorporating the improved means of the present invention
  • FIG. 2 is an enlarged fragmentary cross-section along line II--II of FIG. 1;
  • FIG. 3 is a fragmentary front view of another preferred embodiment of the invention.
  • the illustrated slide fastener comprises a pair of separable stringers generally designated 10 and 11.
  • These stringers comprise flexible stringer tapes 12 and 13 having their opposed longitudinal edges reinforced with beads 14 and 15 to carry rows of predeterminedly spaced, interlocking fastener elements 16.
  • These fastener elements can be clamped or otherwise secured to the beaded edges of the stringer tapes 12 and 13 and are adapted to be progressively engaged and disengaged by a slider 17 slidable therealong to close and open the fastener.
  • a suitable separable bottom end fitting such as the conventional box-and-pin separable coupling may be provided at the bottom end of the fastener to separably connect the stringers 10 and 11.
  • the slide fastener of FIG. 1 is further provided with a slider escape mechanism comprising a cooperative pair of yieldable top stops 18 and 19 mounted on the respective rows of interlocking fastener elements 16 at their upper extremities, and an extra length of fastener elements 20 carried on the beaded edge of the stringer tape 13 as an upward extension of the regular row of fastener elements 16 thereon.
  • the extra length of fastener elements 20 has a top stop 21.
  • the pair of yieldable top stops 18 and 19 is effective to limit the upward or fastener closing movement of the slider 17 along the rows of interlocking fastener elements 16.
  • the top stops 18 and 19 jointly permit the slider to travel therepast and to ride onto the extra length of fastener elements 20 on the stringer tape 13.
  • This invention is directed specifically to means 22 formed at an upper end portion of the stringer tape 12 in opposed relationship to the extra length of fastener elements 20 on the other stringer tape 13, in order that the stringer tape 12 may be readily released by the slider 17 when same is forcibly moved onto the extra length of fastener elements in an emergency.
  • the bead 14 and the adjacent edge portion of the stringer tape 12 are cut off from the aforesaid upper end portion of the tape, as indicated by the imaginary lines 23 in FIG. 1.
  • the length of this cut-off portion 23 should be at least equal to, or preferably suitably longer than, the length of the body of the slider 17.
  • a reinforcing sheet or film 24 of thermoplastic material is then wrapped around the upper end portion of the stringer tape 12 inclusive of its cut-off portion 23 and is heat-sealed thereto as by a suitable heater or by the conventional ultrasonic or high frequency method.
  • the slider 17 which has been in its closed position on the pair of stringers 10 and 11 may be forced upwardly past the pair of yieldable top stops 18 and 19 onto the extra length of fastener elements 20 on the stringer tape 13 in an emergency.
  • the reinforced upper end portion of the other stringer tape 12, having no edge bead 14, is then readily withdrawable from the slider 17 on the extra length of fastener elements 20.
  • the stringers 10 and 11 of the fastener can then be completely spread apart from each other by disengaging the rows of fastener elements 16 without need for pulling the slider 17 down therealong.
  • FIG. 3 illustrates a modification of the preceding embodiment, in which the beaded edge of the upper end portion of the stringer tape 12 is cut off at 23a after attaching the reinforcing sheet or film 24 of thermoplastic material or the like thereto.
  • Other details are exactly as set forth above in connection with FIGS. 1 and 2.
  • the bead and, if desired, the adjacent edge portion of the stringer tape 12 can be removed from its upper end portion either before or after attachment of the reinforcing sheet thereto according to the invention.
